Biological Activity

Dimeric version of R18 peptide (Cat. No. 2144) that binds to 14.3.3 proteins with high affinity. Competitively inhibits 14.3.3-ligand interactions; blocks the ability of 14.3.3 to bind to target proteins such as Raf-1, Bad, ASK1 and exoenzyme S. Induces apoptosis when expressed in COS-7 and various cancer cells.

Cell Cycle & DNA Damage Repair

Cell Cycle & DNA Damage Repair Poster

In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.

Programmed Cell Death

Programmed Cell Death Poster

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.

Apoptosis

Apoptosis Signaling Pathway

Apoptosis is a physiological process for cell death that is critical during aging and development. It may also be referred to as cell 'suicide'. Apoptosis can be triggered by events both inside and outside of the cell.
